Why did Alejandro never come along to collect his money after telling on the Night Stalker? Was he too scared? I remember Stack saying he maybe deceased but also had a family. I think Stack also said there was no foul play suspected. Why would Alejandro be deceased? He was a young man? Anybody have any idea why he never came to collect his money?

maybe the NS caught up with him before

I sort of figured perhaps he might have even been afraid to claim the reward, or didn't otherwise want the publicity.
